Abstract
The invention provides a corrugated porous separation film. A flat film comprises two parallel separation layers, the middle of the two parallel separation layers is provided with support holes, the multiple sequentially arranged support holes form channels, and the outer surface of the flat film is provided with a corrugated support. The corrugated porous separation film is of rectangular structure, and the two parallel separation layers are made in corrugated shape through a spinneret plate. The invention is intended mainly to overcome the defect that a flat film has small filling area and poor anti-pollution capacity; the parallel separation layers form the flat film with two separation layers, the filling area of the flat film is increased, and the middle channels act for supporting and also facilitate outflow of water; the two separation layers are made in the corrugated shape through the spinneret plate, turbulence of a fluid is increased, particle deposition is decreased, and film pollution is decreased. The filling area problem and anti-pollution capacity problem of a flat film component are fully solved.
Description
Technical field
The present invention relates to porous membrane field, more particularly, to a kind of corrugated porous diffusion barrier.
Background technology
Perforated membrane has sieve effect, belongs to pressure-driven, and its separative efficiency is controlled by aperture and the pore-size distribution of film,
It is widely used in purification of water quality, the separation of the industry such as food, pharmacy, biology special type small molecule.
Existing porous-membrane module principal mode has hollow-fibre membrane, capillary-pipe film, tubular membrane, rolled film, Flat Membrane.Various
The membrane module of form respectively has the advantages that oneself and defect, the mainly balance between filling area, price and contamination resistance
With compare.Flat Membrane is easily manufactured, price appropriateness, and contamination resistance is strong, gradually obtains extensive application in porous separation field, but
It is to yet suffer from the not enough energy inferior position weak with contamination resistance of filling area.
The filling area of membrane module largely affects initial investment cost, and contamination resistance is weak can then affect the later stage
Operating cost, filling area and contamination resistance directly affect range of application and the field of membrane module.
The filling area of existing Flat Membrane is little, also needed to water flow passage, and decreased in unit volume between two Flat Membrane
Filling membrane area, increased the price of membrane module.The fluid of Flat Membrane is in laminar condition, and particle deposits, and is easily formed dirty
Dye, contamination resistance is poor, and longtime running increases cost.
Simply hollow fiber film thread in existing Patents, such as 201020131655.X, simply spliced or
Woven tube is merged into one piece of spinning, is difficult to the problems such as solve the sludge accumulation in running, and machine between film silk and film silk
Tool intensity not high it is easy to film silk and film silk phenomenon of rupture occur.
Content of the invention

Explanation, and each embodiment does not constitute the restriction to the embodiment of the present invention.
A kind of end face structure schematic diagram of corrugated porous diffusion barrier provided in an embodiment of the present invention as shown in figure 1, this
Bright embodiment arranges two separating layers being parallel to each other in Flat Membrane, forms the Flat Membrane with two separate layer, increases flat
The filling area of plate film, in the middle setting supported hole of two separating layers being parallel to each other, multiple supported hole structures being arranged in order
Become duct.Above-mentioned supported hole plays the effect supporting Flat Membrane, is also beneficial to water outlet and flows out.On the outer surface of described Flat Membrane
Setting corrugated supporter, constitutes corrugated porous diffusion barrier, this corrugated porous diffusion barrier can be rectangular configuration.
Two separate layer is molded by spinneret corrugated, increases the turbulent flow of fluid, reduce the deposition of particulate matter,
And then minimizing fouling membrane.Fully solve the filling area of plate film assembly and two hang-ups of contamination resistance.
A kind of structural representation of spinneret provided in an embodiment of the present invention as shown in Fig. 2,3 and 4, the spray of this special construction
Filament plate, solves the formation problems of ripple film.The spinneret of this type mainly includes：The distribution structure of casting solution and ripple film
The part such as the stereotyped structure of molding structure, the distribution structure of core liquid and ripple film form.The distribution structure of casting solution includes horizontal stroke
To the multiple casting solution distribution pipes with genesis analysis, the distribution structure of core liquid includes core liquor stream road and core liquid distribution pipe.
Phase method or thermic phase method, low temperature is caused to cause phase method, compound cause phase using above-mentioned special spinneret by non-solvent
Method prepares corrugated supporter and the supported hole with special-shaped aperture, and specific operation process includes：
The casting solution preparing first, by spinning pump, filter filter after enter casting solution distribution structure in, casting
The distribution structure of film liquid plays casting solution and evenly distributes effect in horizontal and vertical.Reserve from the distribution structure of casting solution
Casting solution enters the molding structure of ripple film, and the molding structure of ripple film plays the casting solution evenly distributing just one-step forming, obtains
To casting solution rudimentary model.Distribution structure using core liquid irrigates core liquid, the distribution structure of core liquid toward in casting solution rudimentary model
Play core liquid and evenly distribute effect in horizontal and vertical, formed in the presence of core liquid and support inner duct, finally in ripple film
Stereotyped structure assist the lower and non-solvent of external environment under the influence of, split-phase formation has the ripple film of ripple struction.Casting film
Solvent in liquid spreads to core liquid, and the precipitating reagent in core liquid spreads to casting solution, and this diffusion is referred to as double diffusion.Made by diffusion
Casting solution thread reaches critical concentration, and polymer separates out in solidification core liquid and forms ripple film.
Above-mentioned casting solution material can be Kynoar, polyether sulfone, polysulfones, SPSF or polyether sulfone, polychlorostyrene second

The contamination resistance of the corrugated porous diffusion barrier of the embodiment of the present invention and the Flat Membrane of same recipe tests effect
Contrast as shown in Figure 5, Figure 6, the corrugated porous diffusion barrier of the embodiment of the present invention has that manufacturing price is cheap, filling area is big,
The advantage such as contamination resistance is strong, increased in the corrugated of two separate layer and has filtered area, effectively solving filling area is low
Problem.
Test result shown in Fig. 5, Fig. 6 can be seen that, due to defining the Flat Membrane with two separate layer, ripple
Line shape porous diffusion barrier has good contamination resistance, increases the filling area of Flat Membrane, and middle duct is played support and made
With being also beneficial to water outlet and flowing out；Corrugated in separating layer, increases the turbulent flow of fluid, reduces the deposition of particulate matter, and then reduces film
Pollution；The corrugated of two separate layer increased and filtered area.
In sum, mainly for Flat Membrane, filling area is little for the embodiment of the present invention, the weak shortcoming of contamination resistance, leads to
Cross the separating layer being parallel to each other, form the Flat Membrane with two separate layer, increase the filling area of Flat Membrane, the duct of centre
Play a supporting role, be also beneficial to water outlet and flow out, two separate layer is molded by spinneret corrugated, increase the rapids of fluid
Stream, reduces the deposition of particulate matter, and then reduces fouling membrane.Fully solve the filling area of plate film assembly and contamination resistance
Two hang-ups.
Sludge accumulation phenomenon is avoided using corrugated smooth transition, and monoblock rectangular membrane is exactly one from this, machine
Tool intensity is high.
